Abstract

Die Erfindung betrifft lineare oder verzweigte, primäre Di- oder Polyamine mit endständigen primären Aminogrup­ pen, erhältlich durch Hydrogenolyse von Di- und Poly(-O-­ benzylurethanen) aus Di- und Polyisocyanaten, die in ihren Molekülketten aliphatische, cycloaliphatische, aromatische oder araliphatische Kohlenwasserstoffreste und Polyether-, Polyester- oder Polyetherpolyestersegmente und stets min­ destens zwei Urethangruppen
(-O--NH-)

oder die vorstehend genannten Kohlenwasserstoffreste und mindestens eine Harnstoffgruppe (-NH-CO-NH-), eine Biuretgruppe (-NH-CO--CO-NH-),

eine Allophanat­ gruppe
(-NH-CO--O-)

oder eine Isocyanatgruppe eingebaut enthalten, und Benzylalkohol mit Wasserstoff in Gegenwart von Hydrierkatalysatoren unter Abspaltung von Toluol und Kohlendioxid. The invention relates to linear or branched, primary di- or polyamines with terminal primary amino groups, obtainable by hydrogenolysis of di- and poly (-O-benzylurethanes) from di- and polyisocyanates, which have aliphatic, cycloaliphatic, aromatic or araliphatic hydrocarbon radicals in their molecular chains and polyether, polyester or polyether polyester segments and always at least two urethane groups
(-O - NH-)

or the hydrocarbon radicals mentioned above and at least one urea group (-NH-CO-NH-), a biuret group (-NH-CO - CO-NH-),

an allophanate group
(-NH-CO - O-)

or an isocyanate group built in, and benzyl alcohol with hydrogen in the presence of hydrogenation catalysts with elimination of toluene and carbon dioxide.

Die Di- und Polyamine werden als Härter oder als Modifizierungsmittel für 1,2-Epoxidharze oder für Harze mit Isocyanatgruppen bzw, Isocyanatgruppen liefernden Grup­ pen eingesetzt. The di- and polyamines are called hardeners or as Modifier for 1,2-epoxy resins or for resins with Isocyanate groups or groups supplying isocyanate groups pen used.
